tub diverter installation

Hello. I got the tub diverter off finally. I unscrewed it and screwed it back on, oblivious to the fact that it has a set screw.

Not that it's off, I need to replace it. Would you please give me some pointers and perhaps link to a relevant Youtube video. The pipe you screw it on to is smooth. Please see here:

The old one was probably by American standard. I wouldn't know the model number or anything.

Thanks!

You can find videos online if needed. Make sure the pipe sticking from the wall is clean and smooth with no burrs. The new spout just slides on and you tighten the setscrew to hold it in place. Just make sure you buy the slip on style and not the NPT threaded style spout.

You need a tub spout, not a diverter. You want the type of spout that slips over the pipe and is held in place with a set screw.

Ok. I meant to say tub spout. Do you have a recommendation for a spout? Also, could you give me installation instructions or link to a relevant Youtube video. I think it's a smooth copper pipe.

What about the hole in the wall? Can I fill it with 100% silicone? Some said to do the top 2/3rds of it only without explanation.

I caulk the spout to the wall. Normally I caulk 90% leaving a small opening at the bottom for drainage.

In other words, I don't have to fill that hole?

Also, please note that, after I got a new water heater installed, my pipes start rattling when I turn the shower on if the water is down too low (i.e., too cold). I was thinking that adding silicone to the space between the copper pipe and the wall would help stabilize the pipe.

Rattling is usually caused by the faucet's (cartridge). A resonance can develop at certain pressures and flows.

I see. I think I'm about ready to give this a try. Thanks again.

Well, I have a problem. The right side of the spout was not flush with the wall for some reason. I was thinking that tightening the set screw would do the trick. Well, not only did it not make the spout tighter, it put a dent at the bottom of the copper pipe.

I'm assuming the copper pipe has to be replaced now?

Is it safe to turn on the bathtub water to see if it leaks from that dent?

I have to ask a separate question. When I took my new spout out of the package and pulled the diverter up, it fell down. I tried again and same result.

My old tub spout doesn't do that. That is, when I pull the diverter up, it stays up, even though it has been removed from the copper pipe.

Does this mean that they sold me a bad diverter?

Here are some better looks at the dent in the pipe.

The diverter is held up by water pressure. When you turn the water off it should fall on it's own. Your old one was probably sticking from years of mineral buildup.

Thanks. What about that dent?

Can I turn the water on while the spout is off to see if there is a leak?

Or will the whole pipe have to be replaced?

Update: I ran the water for about 5 minutes and didn't detect a leak. Is there some way to just solidify the dent? Am I good how it is? Please note that I will probably have my bathroom professionally remodeled in a couple of years, which would like include a plumbing update.

The dent is caused by the set screw being overtightened but it usually doesn't hurt anything. To fix it you need to replace the pipe.

I am going to cap the end of the pipe with a shark bite push cap and if the hole isn't leaking I am going to use it. I'm assuming that the water will divert to the shower head.

I have never seen one of those set screw dents leak.

Tub faucets like yours are very simple. The pipe to the shower is always open to the water coming out of the valve. Normally it flows out the tub spout because that is the lowest point (gravity)(path of least resistance). When you pull the knob up it blocks the flow of water out the spout so the water rises in the piping until it reaches the next escape, the shower head. For fun, when running the tub, put your hand over the outlet of the spout to stop the water. In a few seconds the water will come out of the shower and when you remove your hand the shower will stop.

I'll start here because you know the history of this job. The new spout is on. I sealed the gap between the spout and the wall with a red disc seal and silicone on the top.

The only issue is that, when I take a shower, there are two small streams of water that flow from each end of the spout head, which I bought new (Danco).

If I had to hazard a guess, I'd say that that's because one, the other, or both of these things. One, water is dripping through that dent in the pipe. Two, I put the copper pipe too short. It's very close to two inches.

To be clear, there is no water leak when the water is off.

I would like to know what you think the cause of these streams is. That said, my biggest concern is whether I have to do something about those drips. If I'm not running the risk of making matters worse, I'm inclined to just leave it like that. I plan to have the bathroom renovated in a couple of years anyway, and I'm sure that will involve plumbing of that pipe.

I cannot do anything too big on my own right now due to work constraints.

Thanks.

Water should not be coming out the base of the spout. If it is it means the spout is not sealing correctly to the pipe coming from the wall. You definetely do not want any of that water getting into the wall.

It's coming out of the head of the spout, not the base. There is two small streams that come down on both sides of the head when the shower is on, i.e., when the diverter is up.

It's not that I disagree, but a guy said on a Youtube video that it says on the back of the Danco spout that a little water coming from the head of the spout while the shower is on is to be expected.

What is "the head"?

It is normal for a pull up type shower diverter to not seal 100%. So, if you still have water coming out of the spout when showering that is OK.

The end part of the spout, i.e., the farthest part from the wall. The large opening at the end of the spout that the water flows from.

Yes, it is normal for some water to leak out of there when showering. And, that's sorta a good thing. When you are done showering you can just turn the water off. Then the water in the riser to the shower head will slowly leak out the spout until the diverter falls down to the off position (and drains the rest of the water out of the piping) so you don't get sprayed on the back of the head the next time you open the faucet.

That's exactly how it worked. Another DIY successfully completed with the help of this forum. Thank you!
